During the primary cementing, wellbore temperature rises because of hydration heat of cement slurry accompanying its pressure reduction. The combined effect of annular temperature and pressure can change working conditions of casing string. After cementing, these changes are solidified in cementing interval, which affects the performances of casing in its whole life. The data of wellbore temperature response of a hole in primary cementing are obtained by numerical computation and simulation....

During the primary cementing, wellbore temperature rises because of hydration heat of cement slurry accompanying its pressure reduction. The combined effect of annular temperature and pressure can change working conditions of casing string. After cementing, these changes are solidified in cementing interval, which affects the performances of casing in its whole life. The data of wellbore temperature response of a hole in primary cementing are obtained by numerical computation and simulation. Pressure formula is established with a statistical method. The relationship among casing string length, annular temperature and pressure, shear stress along with the surfaces of casing tube is founded using the finite element theory. On the basis above, a finite element solution is obtained. The time dependent stress and strain response in casing string during primary cementing are investigated. Some data about damage of casing can be obtained by numerical computation.

套管柱注水泥结束后 ,由于水化热的作用使水泥浆在胶凝过程中产生升温现象 ,并随之失重。温度、压力的共同作用会使套管柱发生很大的形变。随着水泥的固化 ,这种形变也会被固结在水泥封固段内 ,影响其使用性能。在调研大量资料的基础上 ,利用数值计算方法得到了水泥胶凝过程中温度变化的动态数据。对某油田实测数据进行了统计分析 ,得出了水泥浆失重时的压力计算公式。根据有限元理论 ,推导出套管段长度与温度、压力、水泥及套管表面剪切应力之间的关系式。在此基础上 ,计算得到了水泥浆胶凝过程中套管的动态变化。

There are two principal objectives facing primary cementing operations-casing support and zonal isolation.The later usually raises the most concern and is perhaps the hardest goal to achieve when there is potential for formation gas to migrate into the cement sheath.The challenge for the industry is to achieve a long-term annular cement seal and prevent formation gas entry.The successful handling of gas migration is an evolving process of understanding.The aim of this article is summarize up the causes,consequence,prediction method of gas migration,evaluating the current industry handling methods and the latest methodology development in this area.

在固井作业中有两个最基本的目标 :支撑套管与层间封隔。但层间封隔问题更引人注意 ,特别是当有气体侵入水泥环中的可能时更是难以达到预期目标。怎样取得长期的环空水泥封隔和防止地层气的侵入 ,只有随着对这一问题的理解的不断深入 ,人们才能逐步找出解决这一问题的方法。文中就发生气侵的原因、后果、预测方法、对现行各种解决办法的评价和其最新进展作一概述。

Multi-Primary Cementing Technology is one of the key techniques for Optimal and Fast Drilling Program. The tech-nology has been applied successfully in most of development drilling projects in Bohai Bay in recent year, and it is becoming more ma-tured. This article summarizes briefly the achievements of the technology in Optimal and Fast Drilling Program and expresses system-atically its main points of application in cementing design and well-site cementing operation.
