东南亚,油藏通常呈层状、薄层状且分隔成多个储层。由于成本和钻井时间的限制,对每个主要储层段进行钻杆测试(DST)并不经济。层间压力瞬态测试(IPTT)和深部瞬态测试(DTT)作为更环保的电缆测试方法被引入。本文提供了在同一口井中同时进行IPTT或DTT钻杆测试的实例。

Pairing Wireline Formation Testing With Drillstem Testing Unlocks Potential

This paper compares deep transient testing with drillstem testing in a high- and low-permeability gas reservoir, including test-selection implications and best practices.

In Southeast Asia, reservoirs are frequently laminated, thinly bedded, and compartmentalized. Testing every individual (main) zone with drillstem tests (DSTs) is not economical because of cost and rig-time constraints. Interval pressure transient tests (IPTT) and deep transient testing (DTT) have been introduced as greener alternative wireline-testing methods. This paper provides examples wherein DSTs with either IPTT or DTT have been acquired on the same well.

First, a power planner is run to determine the maximum system power available.
