为解决钻孔过滤器类型、规格和填砾规格、厚度、过滤器有效长度等问题,可先在实验室作试验。例如美国贝克、契夫隆等石油公司为解决井的过滤器和填砾问题已建立大型试验室,用钻孔的模型试验解决了生产实际问题。这种方法同样适用于深水井。值得参考。 一、试验目的 In order to solve the problems of drilling filter type, specification and packing size, thickness, effective length of filter, etc., it can be tested in the laboratory first. For example, oil companies such as Baker and Chevron in the United States have established large-scale laboratories to solve the problem of filters and gravels in wells. Model tests using drill holes have solved practical production problems. This method also applies to deep wells. Worth reference. First, the purpose of the test
