Abstract
An electrical borehole logging tool includes a mandrel 42 around which a plurality of annular electrode members (A0 to A2, M1, M2 etc) and insulating members (such as 63, 65, 67, 69, 71) are alternately stacked to achieve a particular configuration of formation- measuring electrodes. Fluid seals (such as 83, 84) are arranged between adjacent ones of the annular members whereby a fluid tight space 77 is formed between the mandrel and annular members which is filled with silicone oil. The pressure in the space is regulated by means of expansible pressure balancing means comprising an expansion sleeve 106. Pressure of the borehole fluids is transmitted to the sleeve 106 via holes 111 in outer tube 110. A substantially constant compressive pre-stressing force is applied to the stack of annular members by tubular body member 102 in the form of a stiff spring providing an axial force. <IMAGE>
