1 Introduction to the Model LSM-15087 Linear Swell Meter The Linear Swell Meter is designed to test and study the reactivity of shales encountered in oil well drilling. The objective is to apply the information to anticipate and / or correct problem shale encounters, thereby minimizing drilling risks and costs caused by these oftentimes unpredictable materials. Much attention has been given over the years to the development of chemical and mechanical tests and to diagnostics methods that can measure the reactivity of shale. Function Focusing on accepted shale characteristics this general...

test sample can significantly alter the shale reactivity. Increasing the temperature will increase the reactivity and reduce the swelling test time. Swelling reactivity in reconstituted shale core samples for a swell meter test is not only dependent on the type of shale used, but also on the pressure and duration of compaction loading and the initial moisture content.

measure the displacement of the sample in the vertical direction with an accuracy of 0.1 percent. The mechanical restraining force (pre-load) which applied to the shale core sample during the swelling test is 550 grams. Additional pre-load can be applied by the addition of an auxiliary weight. With this weight the total force (preload) is 2000 grams. During a swelling test, the shale core sample, previously equilibrated in a predetermined constant relative humidity environment, is laterally confined by a snug fitting porous sleeve to minimize radial swelling. This sleeve extends slightly...

LSM Software The LSM software provides data acquisition from up to 4 channels of Linear Swell Meters. The test status is summarized in graphic form on the main display, and in text/digital form at the bottom. The time and value at each point along a curve in the graph appears in the top right when the cursor is placed along a graph line. Tests on multiple channels may be identified with each other for reporting purposes by using the identical sample name when starting the tests. RIGCHINA Group Company offers a complete line of instruments for use in testing drilling fluids in accordance...
