前言最初使用的压裂液是炼制油和原油,由于最初担心压裂液与含有非酸性水液的油气贮层接触可能产生不利影响。后来的实验已经证明,用适当的添加剂(粘土控制物质、表面活性剂等),使用水基液能处理大部分油气贮层。在一个已知贮层的压裂处理中,最好是通过实验室地层岩心试验(或者一贯的现场结果)来确定水基压裂液的可用性。当使用油基液时,运用这些评定方法已经使得某些贮层反应最好。目前,使用油基液的压裂施工不到压裂施工总数的10%。 Foreword Initially used fracturing fluids are refinery oils and crude oils, which may be adversely affected by the initial concern that fracturing fluids come into contact with hydrocarbon reservoirs containing non-acidic aqueous fluids. Subsequent experiments have shown that most of the oil and gas reservoirs can be treated with water-based fluids using the appropriate additives (clay-controlled substances, surfactants, etc.). In a fracturing treatment of a known reservoir, it is best to determine the availability of a water-based fracturing fluid by laboratory formation core tests (or consistent field results). The use of these methods of evaluation has made some reservoirs react best when using oil-based fluids. At present, fracturing with oil-based fluids is less than 10% of the total fracturing effort.
