羧甲基羟丙基压裂液体系在长庆华庆油田的应用
Application of low concentration CMHPG fracturing fluid in Huaqing reservoir of Changqing Oilfield
摘要
Abstract
According to the characteristics of low porosity and low permeability in Huaqing Oilfield, a kind of carboxymethyl hydroxypropyl (CMHPG) fracturing fluid was developed with concentration of 0.25%. The fluid has strong sand-carrying ability and through gel breaking. The residue content of CMHPG was only 128 mg/L. And reduce the effect on sand-carrying ability came from high concentration of calcium and magnesium ions in water. It has achieved good application results in Huaqing chang-6 reservoir of Changqing Oilfield. After fracturing transformation, the six months’ average production index of 23 test wells was 1.4 times as high as the compared well of the same well group. Using CMHPG fracturing fluid is one of the highly effective ways to stimulate the low-permeability reservoirs.关键词
