摘　　要：地层测试是油气井工程试油(气)方法之一,由于不同工作制度下测试施工周期变化大,传统的按"层"或"天"为计量单位的单一定价法与测试工艺、生产消耗不完全匹配,工程造价往往偏离生产实际,在实际应用中存在3点不足:①价格可比性差,不利于促进公平竞争;②造价不可控,不利于建设单位投资控制;③通用性差,与新工艺新技术不相适应。通过引入二部定价法,将测试价格分为测试日费和测试层费两部分,即地面设备、操作人员等发生的费用按时间计费;测试器等入井工具按测试层数计费。这种计价方法具有4个方面的优点:①采用测试日费可以反映不同测试工作制度下的工程造价差异;②测试工具按层计费符合测试器摊销行业规定;③测试工程量可以准确计量,测试价格具有稳定性和可比性;④能够适应不同测试工艺和地质条件下的地层测试计价。采用二部定价法提高了地层测试计价的科学性,有利于企业精细化管理,促进测试新技术的推广应用,同时也可以满足未来工程量清单计价发展要求。Formation testing is one of the oil （gas） testing methods in oil and gas well engineering. The testing periods vary largely in different working systems, so the traditional single pricing method with a layer or a day as the metering unit can＇t completely match the testing process and production consumption. When it is practically applied, the engineering costs are frequently different from the practical production costs, and three weak points are presented. The first one is the poor price comparability, which is unfavorable for fair competition. The second one is the uncontrollable cost, which is adverse to the investment control of construction units. And the third one is the poor commonality, so it is not applicable to new processes and technologies. By introducing two-part pricing method, the testing cost is divided into two parts, i.e. day-based testing cost and layer-based testing cost. It means that the expenses for surface equipment and operation staff are charged based on time and the costs of downhole tools （e.g. testers） are charged based on layer numbers. This two-part pricing method presents four strong points. First, the engineering cost difference in different testing working systems can be reflected by day-based testing costs. Second, the layer-hased testing cost is accordant with the industry stip- ulations of tester amortization. Third, the engineering amount can be measured accurately and testing price is stable and comparable. And fourth, it is adaptable to formation test pricing with different testing processes and geologic conditions. By means of the two- part pricing method, the formation testing pricing is scientifically improved, fine enterprise management is enhanced, new testing technologies are applied and popularized, and the development requirement for engineering amount list pricing can be satisfied.
