产液量与井温变化关系研究及应用

Study and Research of the Relationship between Liquid Production Capacity and Temperature Change

以溶缝洞型碳酸盐岩为主的塔河油田,多数井在钻井放空漏失或酸压后直接投产,从而缺少裸眼井测井资料,对产液量计算造成极大困难。由于孔隙结构的分布复杂,原始储层温度在纵向和横向上分布均极为复杂。酸液或泥浆压井液的注入导致本已复杂的温度场更加紊乱,需要对温度异常进行分析。在塔河油田中由于多种因素影响,很多生产井的流量无法测量。本文首次针对塔河油田不同区块给出匹配计算参数,提出适合该油田产液量计算的方法。

Tahe oilfield is mainly composed by soluble seam hole carbonate.Most of the Wells are put directly into production with the drilling vent leakage or after acid fracturing,so the lack of openhole logging data causes great difficulties to the liquid producing capacity calculation.Due to the pore structure distribution is complicated,the original reservoir temperature in the vertical and horizontal distribution are very complex.The injection of acid and mud killing makes the complex temperature field more disorder,the temperature needs anomal analysis.Because of many factors in Tahe oilfield,the flow of many production wells cannot be measured.This paper gives the matching calculation parameters of different block of Tahe oilfield and puts forward the calculation method suitable for the oilfield produced fluid volume.
