The Sanshandao gold mine is situated on the seashore frontier of the Laizhou Bay in Sandong Province, the engineering geology and hydrogeology conditions of the mine area are more complex. For this reason, there exist some specific geoengineering problems for underground mining of the gold mine. In this paper the characteristics of stress field are studied by using analysis method of geomechanical structural lines, in situ stress measurement and experiment method of Kairser effect of acoustic emission, respectively. The results suggest that the current tectonic stress in the mine area is N40°E or so, σNE = 110 bar or so,σNE : σV : σNW = 1 : 0. 9 : 0. 65. This provides basic mechanical parameters or the stability evaluation of the underground mining.

三山岛金矿位于山东省莱州湾畔,矿区的工程地质条件及水文地质条件比较复杂,因此对于矿山地下开采存在某些特殊的地质工程问题。本文分别来用地质力学构造线分析方法,现场地应力量测及声发射凯萨尔效应实验方法,研究了矿区的地应力场特性。结果表明,矿区的地质构造应力为N40°E左右,σNE=110bar左右,σNE:σV:σNw=1:0.9:0.65。这为矿山地下开采的稳定性评价提供了基本的力学参数。

Geologic setting is complicate in Sichuan basin. Due to unforeseeable engineering geology problems that make the discrepancy of real drilling and design, and results in drilling complication and trouble. It not only endangers safety drilling and realization of geologic target, but also restricts seriously the improvement of drilling speed and increases drilling cost. The paper analyses the main engineering geology problems of deep drilling and their features in Sichuan natural gas well, such as abnormal formation pressure,sidewall unstability, and reservoir damage etc., and proposes preventive measures.At the same time, the paper also proposes that treatment the relation of four pressures well (formation pressure, caving pressure, leakage pressure and drilling fluid pressure) and analysis drilling engineering geology problems during drilling design and operation are very important. It is key of improvement design quality and realization safety drilling. Drilling engineering is special geologic engineering. The establishment of Drilling Engineering Geology has important significance for the development of drilling technology and improvement of drilling benefit.

四川盆地天然气深井钻井地质条件复杂 ,由于不能预见的工程地质问题造成实钻与设计的差异并导致严重的钻井复杂与事故 ,不仅危及钻井安全和地质目标的实现 ,也严重制约钻井速度的提高 ,显著增加钻井成本 ,这是四川天然气深井钻井最突出的矛盾。文中分析了四川天然气深井钻井主要工程地质问题 (异常地层压力、井壁不稳定、地层自然造斜和储层伤害等 )及其特点 ,提出了预防和处理主要钻井工程地质问题的措施。在钻井设计和施工作业中做好钻井工程地质问题分析和跟踪评价 ,特别是处理好四个压力 (地层压力、坍塌压力、漏失压力和钻井液柱压力 )的关系 ,是提高设计质量 ,实现安全顺利钻井的根本保证。钻井工程是特殊的地质工程 ,建立《钻井工程地质学》这一新的专业基础学科对钻井技术发展和钻井效益的提高都有重要的意义

The reservoir in Caracoles oil field in Venezuela is characterized by low pressure and high permeability. Although the perfect cementing measures have been adopted, the cementing job quality couldn’t meet the needs of oil field development yet. The demands for the cementing job quality depend on the special geological and engineering conditions in the oil field. They include that, while a good interzonal plugging-up is realized, a fine pay zone interface cement bond must be also realized; a design plan, by which the cementing job quality may be evaluated in advance, should be utilized so as to well control operation quality; and the gas channelling induced by undetected slurry leakage should be prevented. The cementing job quality was successfully controlled by means of carrying out the cementing design plan of wall shear stress and the leakproof method by raising slurry viscosity. According to the examination results of the main payzones in 20 wells by applying 3 logging methods, i.e. CBL, VDL and SBT, it was indicated that the high-quality rate of well cementing was 100% and the high-quality rate and qualification rate of well cementing of all reservoirs were 90.75% and 96.23% respectively, therefore the cementing technology in the field was advanced and applicable. These technical results achieved are of important reference value for solving cementing difficulties of the adjustment wells in old field, the exploration wells in new area and the wells in underground gas storage reservoir.

委内瑞拉的Caracoles油田属低压高渗油田,尽管已经采取了完善的固井技术措施,但固井质量仍然不能满足油田开发要求。该油田特殊的地质、工程条件决定了其固井质量需求:在实现良好层间封隔的同时,实现层内界面胶结良好;采用可以对固井质量进行预评估的设计方法以更好的控制施工质量;防止由于井下发生井口难以观察到的渗漏诱发的气窜。通过实施壁面剪应力固井设计方法和提高水泥浆粘度的防漏方法,成功实现了对固井质量的控制。在20口井的施工结果表明:对主力产层CBL、VDL和SBT三项测井检查的固井质量优质率达到了100%,全部储层的固井质量优质率90.57%,合格率的96.23%。该油田的固井技术工作充分体现了先进、适用的特点。取得的技术成果对于解决老油田的调整井固井难题、新区探井的固井难题和储气库固井难题等具有重要参考价值。
