An organboroziconate complex of boron to zirconium ratio 40 is recommended as crosslinker OBZ 1 for plant gum hydrofracturing fluids. An experimental hydroxypropyl guar (HPG)/OBZ 1 gelled fluid has much higher heat and shear resistance than HPG/B 10 (organoborate complex) and HPG/SL 10 (organozirconate complex) gelled fluids do. HPG/OBZ 1 gel maintains viscosity 200 mPa s after being sheared at 170 s -1 and 140℃ over 2 hrs and has good filtrate loss properties. The damage to core permeability...

An organboroziconate complex of boron to zirconium ratio 40 is recommended as crosslinker OBZ 1 for plant gum hydrofracturing fluids. An experimental hydroxypropyl guar (HPG)/OBZ 1 gelled fluid has much higher heat and shear resistance than HPG/B 10 (organoborate complex) and HPG/SL 10 (organozirconate complex) gelled fluids do. HPG/OBZ 1 gel maintains viscosity 200 mPa s after being sheared at 170 s -1 and 140℃ over 2 hrs and has good filtrate loss properties. The damage to core permeability caused by broken HPG/OBZ 1 gel is much less than that by brocken HPG/SL 10 and is slightly higher than that by broken HPG/B 10 and HPG/borate gels. The crosslinking mechanizms are discussed.

The scale is one of causes led to plugging water injectors. Based on the scale index (Langlier) and thermodynamic solubility method (skillman, et al), the paper predicts the scaling trends of CaCO3 and CaSO4 in SZ 36 - 1 Oil Field respectively and, through the dynamic scaling test on cores, studies the damage to core permeability when injected water is mixed with formation water during modeling for SZ 36 - 1 Oil Field.

结垢是注水井堵塞的主要原因之一。本文以 Lauglier的结垢指数法和Skilman 等人的热力学溶解度法,分别预测了绥中 36-1油田的CaCO_3 和CaSO-4 结垢趋势,并通过室内岩芯动态结垢试验,研究了绥中36-1油田模拟注入水与地层水相混时对岩芯渗透率的伤害情况。

On the basis of evaluation of the damage degrees of often-used additives to synthetic cores by using HPHT danamic filter press and permeability gradient tester, 3 drilling/completion fluids systems are formulated by using the optimum additives. Their dynamic/static filtration laws and damage to cores are studied. The results show low dynamic/static filtration, large difference between the structures of dynamic/static filter cakes and less damage to cores. If JDB is added in these 3 systems,...

On the basis of evaluation of the damage degrees of often-used additives to synthetic cores by using HPHT danamic filter press and permeability gradient tester, 3 drilling/completion fluids systems are formulated by using the optimum additives.

If JDB is added in these 3 systems, much better reservoir protection result will be achieved.
